As you can see, it has a feel/vibe similar to the cover of The Little Sleep. Sleep for everyone!

Cue the official book description:

Mark Genevich, narcoleptic detective, is caught between friends and a police investigation in this wickedly riveting PI novel with a twist—a follow-up to The Little Sleep

Mark Genevich is stuck in a rut: his narcolepsy isn’t improving, his private-detective business is barely scraping by, and his landlord mother is forcing him to attend group therapy sessions. Desperate for companionship, Mark goes on a two-day bender with a new acquaintance, Gus, who is slick and charismatic—and someone Mark knows very little about. When Gus asks Mark to protect a friend who is being stalked, Mark inexplicably finds himself in the middle of a murder investigation and soon becomes the target of the police, a sue-happy lawyer, and a violent local bouncer. Will Mark learn to trust himself in time to solve the crime—and in time to escape with his life?

Written with the same “witty voice that doesn’t let go”* that has won Paul Tremblay so many fans, No Sleep Till Wonderland features a memorable detective whose only hope for reconciling with his difficult past is to keep moving—asleep or awake—toward an uncertain future.
